Heat-sensitive lithographic printing plate precursor

A positive-working heat-sensitive lithographic printing plate precursor comprising

• a support having a hydrophilic surface or which is provided with a hydrophilic layer,
• a coating which does not dissolve in an aqueous alkaline developer in the unexposed areas and which becomes soluble in an aqueous alkaline developer in the exposed areas, and
• an intermediate layer between said hydrophilic surface or said hydrophilic layer and said coating,
• wherein said intermediate layer comprises a first polymer having a first monomeric unit which is vinylcaprolactam,
• wherein said first polymer comprises said first monomeric unit in an amount between 3 mol % and 75 mol %,
• wherein said first polymer further comprises a second monomeric unit of formula II:
• wherein
• R6, R7 and R8 are independently a hydrogen atom or an optionally substituted alkyl group,
• R9 is a hydrogen atom, or an optionally substituted alkyl, cycloalkyl, aryl or arylalkyl group,
• R10 is represented by formula IV:
• wherein
• * denotes the position of attachment of the group R10 to the nitrogen atom in formula II,
• R13 and R14 are independently a hydrogen atom, or an optionally substituted alkyl, alkenyl, cycloalkyl, aryl, arylalkyl or heteroaryl group, or wherein R13 and R14 together form a cyclic structure.
